Rachael Leigh Cook, 44, and Freddie Prinze Jr, 48, have a She's All That reunion... 25 years after the hit teen film was released

Rachael Leigh Cook and Freddie Prinze Jr had a She's All That reunion this week.

It has been 25 years since the hit teen film was released.

The actors were seen side by side at the premiere of Freddie's wife Sarah Michelle Gellar at The Girl in the Pool world premiere screening in Los Angeles on Wednesday evening.

She's All That was an instant hit in 1999.

It is about a high school hotshot Zach Siler (Prinze Jr.) who is dumped by his cheerleader girlfriend, Taylor (Jodi Lyn O'Keefe).

Desperate to revive his fading reputation, Siler agrees to a seemingly impossible challenge. He has six weeks to gain the trust of nerdy outcast Laney Boggs (Cook) -- and help her to become the school's next prom queen.

Rachael, 44, looked youthful in an off-the-shoulder sweater, jeans and boots.

Freddie, 48, who stars as the lead character Thomas in the film, opted for a smart bomber jacket and a pink T-shirt for the premiere.

The official trailer for the The Girl In The Pool dropped last month, and sees Freddie reunite with Monica Potter, 52, his co-star in the 2001 film Head Over Heels.

The I Know What You Did Last Summer star, 48, plays Thomas, a successful man married to Kristen (Potter) - but also engaging in an extramarital affair with a younger woman.

Thomas' mistress visits him at his home on his birthday, but things take a deadly turn when she is discovered dead by their pool. Panicked, Thomas hides her body in a trunk in the backyard - moments before his wife surprises him with a birthday party in their backyard.

The trailer captures a desperate Thomas attempting to keep the body hidden from guests at his home.

The trailer begins with Thomas' mistress stopping by his home and stripping down into her underwear as they make out by the pool.

But things take a turn for the worse as his mistress is then seen laying on the floor, seemingly deceased, with blood streaked across her face and pooled up on the floor. 

It remains unclear how the woman died, but Thomas decides to hide her body. 

The panicked man is seen placing her body in a storage trunk in his backyard. 'I love you,' he says. 'But I have a family.'

Prinze Jr was joined at the event by his wife Sarah Michelle Gellar

But not long after the incident, he is surprised with a crowd of loved ones in his backyard by his wife. 

Despite his family being there for him, Thomas is anxious for the festivities to end. 'How much longer do we have to do this?' he asks his wife. 

'Why are you asking me that?' Kristen asks. 

In the bathroom, Thomas attempts to calm himself down, telling himself in the mirror, 'Just breathe, everything's going to be OK.' 

But his father-in-law, already suspicious of Thomas, overhears the conversation. 

'Were you talking to yourself or your mistress?' his father-in-law asks as Thomas emerges from the bathroom. 

Thomas' anxious behavior raises eyebrows from another guest at the party who tells him, 'I've been watching you all night looking over your shoulder.' 

An unexpected guest also arrives to the party - the man married to Thomas' mistress. 

The concerned husband tells Thomas and Kristen that he has been unable to find his wife, but her Uber account revealed she was last dropped off at Thomas' residence.

'The last location she came to was here but her phone keeps going to voicemail,' Kevin explains. 

Thomas returns to the chest where he placed his mistress and finds her phone, ringing with a phone call from Kevin. 

Fans will have to wait until July 26 to see how the thriller resolves.
